Not sure why, but many times using the Convert all Text to Outlines leaves some fonts live. Is there a threshold or reason why some would be left untouched? I can always use the Select Object tool and select all then manually Text->Convert to Outlines but it's a pain when there's multiple pages to be done.

Our Sign Shop wants all fonts converted, as do most outside sign vendors.

I've wondered about this myself.Not sure why, but I always thought it was a licensing issue (by the font creator).Like some fonts can't be embedded in a pdf, some can't print, etc.Usually on a font that was meant to be used only on a Web site and not for print.
